CAT NO: DIDACTICNLE-Export-210013
Test Stand for Control Valves- Engineering Lab Training Systems.
Technical Description
Control valves are an essential part of
process and chemical engineering. The connection between controller and
plant is realised with control valves as actuators. Control valves are
usually used to regulate flows of gases or liquids. Optimum control loop
design depends on a sound knowledge of control valve behaviour as well
as a knowledge of the controlled system's response.
This mobile test
stand allows to investigate and study control valves of different
types. For this purpose the valve is installed in a closed water circuit
with a pressure pump and a supply tank. Flow rate and pressure drop
across the valve are measured. The trigger signal is generated by
potentiometers and indicated on a display. Electrically operated motor
valves can be investigated as well as pneumatic control valves. A data
acquisition system can be used to record and evaluate characteristics
and step responses on a PC.
